Problem pulling any arm64v8/python images #933

Closed waynePovey closed 1 week ago

waynePovey commented 1 week ago

Hi,

As of this morning (earliest known failure was about 09:00UTC but working fine yesterday), our Github docker build has been unable to pull the arm64v8/python:3.10-bullseye image, though on further investigation I am unable to pull any of the arm64v8/python images even on my local machine. I receive the following error:

Using default tag: latest
latest: Pulling arm64v8/python
no matching manifest for linux/amd64 in the manifest list entries

Any assistance you could provide would be greatly appreciated. Thanks.

You should be using the multi-arch index and specify the arch via the --platform arg.

docker pull --platform linux/arm64/v8 python

or

docker run --platform linux/arm64/v8 python

Hi Laurent,

Can you explain how that would translate to pulling it using the FROM command in Dockerfile?

This is how I'm using it in my Dockerfile FROM arm64v8/python:3.10-bullseye

and according to the docs this is correct approach and was working fine until this morning https://hub.docker.com/r/arm64v8/python

Do you know what's changed?

We've been slowly moving Official Images to a new build process and moved python yesterday, so now the arch-specific namespaces are an image index because they include attached provenance/sbom metedata.

https://explore.ggcr.dev/?image=arm64v8%2Fpython%3A3.10-bullseye

So in a Dockerfile, that would be the following (or without --platform ... and build on an arm64v8 host):

FROM --platform=linux/arm64/v8 arm64v8/python:3.10-bullseye

OK, that's great. Thanks, both of you for the quick responses. I'll make that change tomorrow.

after changes the base image docker build,

FROM --platform=linux/arm64/v8 arm64v8/python:3-alpine
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
CMD [ "python", "./CMS_Script.py" ]

following is the issue,

ERROR: failed to solve: process "/bin/sh -c pip install --no-cache-dir -r requirements.txt" did not complete successfully: exit code: 1

@Prasad1008 is it possible that some of the dependencies you are trying to get need to be built?
